The fault line is located in the towns of Inabanga, Loon and Maribojoc, three municipalities that were badly hit by the earthquake that killed at least 200 people.
Phivolcs said the earthquake had caused a general uplift of three-fourths of Bohol island and pushed the southwestern part of the province toward Cebu by 55 centimeters.
The coastline in Maribojoc has risen and appears to have reclaimed 55 centimeters of land.
